- Make fingerprint and key ID computation async, and rely on Web Crypto
for hashing if available
- Always set fingerprint and keyID on key parsing / generation
- Introduce `*KeyPacket.computeFingerprint()` and
`*KeyPacket.computeFingerprintAndKeyID()`
- Change `getKeyID` and `getFingerprint*` functions to return the
pre-computed key ID and fingerprint, respectively
- Make `PublicKeyPacket.read` async
- Use PascalCase for classes, with uppercase acronyms.
- Use camelCase for function and variables. First word/acronym is always
lowercase, otherwise acronyms are uppercase.
Also, make the packet classes' `tag` properties `static`.
- Add `config.rejectPublicKeyAlgorithms` to disallow using the given algorithms
to verify, sign or encrypt new messages or third-party certifications.
- Consider `config.minRsaBits` when signing, verifying and encrypting messages
and third-party certifications, not just on key generation.
- When verifying a message, if the verification key is not found (i.e. not
provided or too weak), the corresponding `signature` will have
`signature.valid=false` (used to be `signature.valid=null`).
`signature.error` will detail whether the key is missing/too weak/etc.
Generating and verifying key certification signatures is still permitted in all cases.
- Rename `config.compression` to `config.preferredCompressionAlgorithm`
- Rename `config.encryptionCipher` to `config.preferredSymmetricAlgorithm`
- Rename `config.preferHashAlgorithm` to `config.preferredHashAlgorithm`
- Rename `config.aeadMode` to `config.preferredAeadAlgorithm`
- When encrypting to public keys, the compression/aead/symmetric algorithm is selected by:
- taking the preferred algorithm specified in config, if it is supported by all recipients
- otherwise, taking the "MUST implement" algorithm specified by rfc4880bis
- When encrypting to passphrases only (no public keys), the preferred algorithms from `config` are always used
- EdDSA signing with a hash algorithm weaker than sha256 is explicitly disallowed (https://tools.ietf.org/id/draft-ietf-openpgp-rfc4880bis-10.html#section-15-7.2)
Refactor functions to take the configuration as a parameter.
This allows setting a config option for a single function call, whereas
setting `openpgp.config` could lead to concurrency-related issues when
multiple async function calls are made at the same time.
`openpgp.config` is used as default for unset config values in top-level
functions.
`openpgp.config` is used as default config object in low-level functions
(i.e., when calling a low-level function, it may be required to pass
`{ ...openpgp.config, modifiedConfig: modifiedValue }`).
Also,
- remove `config.rsaBlinding`: blinding is now always applied to RSA decryption
- remove `config.debug`: debugging mode can be enabled by setting
`process.env.NODE_ENV = 'development'`
- remove `config.useNative`: native crypto is always used when available
`key.isDecrypted()` now returns true if either the primary key or any subkey
is decrypted.
Additionally, implement `SecretKeyPacket.prototype.makeDummy` for encrypted
keys.
- Changes `openpgp.generateKey` to accept an explicit `type` parameter,
instead of inferring its value from the `curve` or `rsaBits` params
- Introduces `config.minRsaBits` to set minimum key size of RSA key generation
- Remove the boolean return value of various internal functions that throw on
error (the returned value was unused in most cases)
- Update and fix type definitions
- Store private and public params separately and by name in objects,
instead of as an array
- Do not keep params in MPI form, but convert them to Uint8Arrays when
generating/parsing the key
- Modify low-level crypto functions to always accept and return
Uint8Arrays instead of BigIntegers
- Move PKCS1 padding to lower level functions
Also, switch from returning false to throwing errors in most verify*()
functions, as well as in `await signatures[*].verified`, in order to be
able to show more informative error messages.
This also has the effect that we only throw on them when trying to use
the key, instead of when parsing it, and that we don't throw when the
authorized revocation key is specified in a separate direct-key
signature instead of a User ID self-signature (the spec only specifies
including it in a direct-key signature, so that means that we
effectively don't reject them anymore. This is because users that
wanted to use the key, could remove this separate signature, anyway.)
